摘要:

In brief:This study of 13 male and 14 female members of the US Nordic Ski Team was conducted to analyze the nutrient content of their diet. The skiers recorded four sets of three-day dietary data during a year of training and competition. The results showed high calorie intake, as expected. However, fat intake was higher and carbohydrate intake lower than recommended amounts for optimal health and athletic performance. Iron intake by female skiers consistently failed to meet recommended levels, while cholesterol intake exceeded levels considered optimal. Intake of other nutrients reviewed in this report easily met recommended levels.

摘要:

In brief:Seventeen male collegiate swimmers were studied before, during, and after 14 days of reduced training (tapering). Maximal arm power was measured using a bio- kinetic swim bench and during a tethered (power) swim test, and each swimmer also swam 200 yards (182.9 meters) at an evenly paced velocity corresponding to 90% of his best performance of the season. Tapering had no influence on postexercise acid-base balance, but there was a significant increase (p<.05) in power output on both the biokinetic swim bench and the power swim test. Performance times improved an average of 3.1%. The improvements are in part due to significant gains in muscular power.

摘要:

In brief:The authors surveyed 135 instructors about the incidence of injuries and associated factors related to aerobic dance. The instructors had a high number of overuse injuries. Many instructors and students were dancing on nonresilient surfaces and were wearing inappropriate shoes. Many instructors may have exceeded their limits of tolerance to mechanical impact shock trying to maintain high levels of aerobic exercise.

摘要:

In brief:During an 18-month period 61 patients who had problems associated with aerobic dance were evaluated. Fifty-four had overuse injuries, including all but two of the 24 patients who were instructors. The authors used three-phase radionuclide scintigraphy to evaluate some of the injuries and prescribed balanced orthoses for the management of pain related to lower extremity malalignment. Most of the injuries occurred when people began exercising vigorously after a period of inactivity.

摘要:

In brief:In this study shoes, floor types, and individual physical differences were evaluated for their effects on aerobic dance injuries. The injury frequency was 75.9% for instructors and 43.3% for students. The shin was the most common site of injury in both groups. Overall, 60% of the injuries in the student group and 52% of injuries in the instructor group occurred below the knee. Most injuries were not debilitating, and few required medical treatment. The authors concluded that resilient but stable floor surfaces, proper shoes, and moderating the frequency of participation can prevent injuries in aerobic dance.
